"It was my assessment that [the complainant] would not have been able to deal with further questions from people like us that would have added anything useful to the material with which you have to work. In such circumstances there is a potential for imbalance in the evidence, to which the jury needs to be alert, and if you think there was any disadvantage to the defence from [the complainant's] inability to participate in further questioning, then you should make an appropriate allowance for that in your deliberations. In addition, you should consider carefully the points which are set out in the document which the defence put before you on the morning after [the complainant] has given evidence."
"... and as I shall remind you tomorrow, it is very important, since you will be seeing part of the evidence for the prosecution again, that you should not allow the replaying of the video recording to give an undue significance to that part of the evidence. It will be very important that you keep it in proportion, given that you will be having the opportunity to view a second time and to hear a second time one of the witnesses in the case. So what I will need you to understand is that you should therefore guard very carefully against giving disproportionate, in other words unfair weight, to the evidence of a witness whom you have had the opportunity to hear twice, in contrast to any other witness in the case. In anticipation of your seeing [the complainant's] evidence again, I will call your attention now to the document in which the defence set out material that they would have raised, if it had been possible were this, for example, a case in which there had been no such problem; the material that they would have addressed one way or another in the course of cross-examination. So bear that carefully in mind after tomorrow when you have seen [the complainant's] video replayed."
"(1) At every stage in criminal proceedings all persons are (whatever their age) competent to give evidence. ... (3) A person is not competent to give evidence in criminal proceedings if it appears to the court that he is not a person who is able to - (a) understand questions put to him as a witness, and (b) give answers to them which can be understood."
"(1) Any question whether a witness in criminal proceedings is competent to give evidence in the proceedings, whether raised - (a) by a party to the proceedings, or (b) by the court of its own motion, shall be determined by the court in accordance with this section. (2) It is for the party calling the witness to satisfy the court that, on a balance of probabilities, the witness is competent to give evidence in the proceedings. (3) In determining the question mentioned in subsection (1) the court shall treat the witness as having the benefit of any directions under section 19 [special measures] which the court has given, or proposes to give, in relation to the witness. (4) Any proceedings held for the determination of the question shall take place in the absence of the jury (if there is one). (5) Expert evidence may be received on the question. (6) Any questioning of the witness (where the court considers that necessary) shall be conducted by the court in the presence of the parties."
"38. These statutory provisions are not limited to the evidence of children. They apply to individuals of unsound mind. They apply to the infirm. The question in each case is whether the individual witness, or, as in this case, the individual child, is competent to give evidence in the particular trial. The question is entirely witness or child specific. There are no presumptions or preconceptions. The witness need not understand the special importance that the truth should be told in court, and the witness need not understand every single question or give a readily understood answer to every question. Many competent adult witnesses would fail such a competency test. Dealing with it broadly and fairly, provided the witness can understand the questions put to him and can also provide understandable answers, he or she is competent. If the witness cannot understand the questions or his answers to questions which he understands cannot themselves be understood he is not. The questions come, of course, from both sides. If the child is called as a witness by the prosecution he or she must have the ability to understand the questions put to him by the defence as well as the prosecution and to provide answers to them which are understandable. The provisions of the statute are clear and unequivocal, and do not require reinterpretation. (R v MacPherson [2006] 1 CAR 30: R v Powell [2006] 1 CAR 31: R v M[2008] EWCA Crim 2751 and R v Malicki[2009] EWCA Crim 365 .) 39. We should perhaps add that although the distinction is a fine one, whenever the competency question is addressed, what is required is not the exercise of a discretion but the making of a judgment, that is whether the witness fulfils the statutory criteria. In short, it is not open to the judge to create or impose some additional but non-statutory criteria based on the approach of earlier generations to the evidence of small children. In particular, although the chronological age of the child will inevitably help to inform the judicial decision about competency, in the end the decision is a decision about the individual child and his or her competence to give evidence in the particular trial. 40. We emphasise that in our collective experience the age of a witness is not determinative on his or her ability to give truthful and accurate evidence. Like adults some children will provide truthful and accurate testimony, and some will not. However children are not miniature adults, but children, and to be treated and judged for what they are, not what they will, in years ahead, grow to be. Therefore, although due allowance must be made in the trial process for the fact that they are children with, for example, a shorter attention span than most adults, none of the characteristics of childhood, and none of the special measures which apply to the evidence of children carry with them the implicit stigma that children should be deemed in advance to be somehow less reliable than adults. The purpose of the trial process is to identify the evidence which is reliable and that which is not, whether it comes from an adult or a child. If competent, as defined by the statutory criteria, in the context of credibility in the forensic process, the child witness starts off on the basis of equality with every other witness. In trial by jury, his or her credibility is to be assessed by the jury, taking into account every specific personal characteristic which may bear on the issue of credibility, along with the rest of the available evidence. 41. The judge determines the competency question, by distinguishing carefully between the issues of competence and credibility. At the stage when the competency question is determined the judge is not deciding whether a witness is or will be telling the truth and giving accurate evidence. Provided the witness is competent, the weight to be attached to the evidence is for the jury. 42. The trial process must, of course, and increasingly has, catered for the needs of child witnesses, as indeed it has increasingly catered for the use of adult witnesses whose evidence in former years would not have been heard, by, for example, the now well understood and valuable use of intermediaries. In short, the competency test is not failed because the forensic techniques of the advocate (in particular in relation to cross-examination) or the processes of the court (for example, in relation to the patient expenditure of time) have to be adapted to enable the child to give the best evidence of which he or she is capable. At the same time the right of the defendant to a fair trial must be undiminished. When the issue is whether the child is lying or mistaken in claiming that the defendant behaved indecently towards him or her, it should not be over-problematic for the advocate to formulate short, simple questions which put the essential elements of the defendant's case to the witness, and fully to ventilate before the jury the areas of evidence which bear on the child's credibility. Aspects of evidence which undermine or are believed to undermine the child's credibility must, of course, be revealed to the jury, but it is not necessarily appropriate for them to form the subject matter of detailed cross-examination of the child and the advocate may have to forego much of the kind of contemporary cross-examination which consists of no more than comment on matters which will be before the jury in any event from different sources. Notwithstanding some of the difficulties, when all is said and done, the witness whose cross-examination is in contemplation is a child, sometimes very young, and it should not take very lengthy cross-examination to demonstrate, when it is the case, that the child may indeed be fabricating, or fantasising, or imagining, or reciting a well rehearsed untruthful script, learned by rote, or simply just suggestible, or contaminated by or in collusion with others to make false allegations, or making assertions in language which is beyond his or her level of comprehension, and therefore likely to be derived from another source. Comment on the evidence, including comment on evidence which may bear adversely on the credibility of the child, should be addressed after the child has finished giving evidence. 43. The competency test may be re-analysed at the end of the child's evidence. This extra statutory jurisdiction is a judicial creation, clearly established in a number of decisions of this court (R v MacPherson: R v Powell: R v M: R v Malicki; see to the contrary effect DPP v R[2007] EWHC 1842 (Admin) ), where it was emphasised that an asserted loss of memory by a witness does not necessarily justify the conclusion that the appropriate level of understanding is absent). If we were inclined to do so, and we are not, it would be too late to question this jurisdiction. This second test should be viewed as an element in the defendant's entitlement to a fair trial, at which he must be, and must have been, provided with a reasonable opportunity to challenge the allegations against him, a valuable adjunct to the process, just because it provides an additional safeguard for the defendant. If the child witness has been unable to provide intelligible answers to questions in cross-examination (as in Powell) or a meaningful cross-examination was impossible (as in Malicki) the first competency decision will not have produced a fair trial, and in that event, the evidence admitted on the basis of a competency decision which turned out to be wrong could reasonably be excluded under section 78 of the 1984 Act. The second test should be seen in that context, but, and it is an important but, the judge is not addressing credibility questions at that stage of the process any more than he was when conducting the first competency test."
"All witnesses, including the defendant and defence witnesses, should be enabled to give the best evidence they can. In relation to young and/or vulnerable people, this may mean departing radically from traditional cross-examination. The form and extent of appropriate cross-examination will vary from case to case. For adult non vulnerable witnesses an advocate will usually put his case so that the witness will have the opportunity of commenting upon it and/or answering it. When the witness is young or otherwise vulnerable, the court may dispense with the normal practice and impose restrictions on the advocate 'putting his case' where there is a risk of a young or otherwise vulnerable witness failing to understand, becoming distressed or acquiescing to leading questions. Where limitations on questioning are necessary and appropriate, they must be clearly defined. The judge has a duty to ensure that they are complied with and should explain them to the jury and the reasons for them. If the advocate fails to comply with the limitations, the judge should give relevant directions to the jury when that occurs and prevent further questioning that does not comply with the ground rules settled upon in advance. Instead of commenting on inconsistencies during cross-examination, following discussion between the judge and the advocates, the advocate or judge may point out important inconsistencies after (instead of during) the witness's evidence. The judge should also remind the jury of these during summing up. The judge should be alert to alleged inconsistencies that are not in fact inconsistent, or are trivial."
